A plastic float ball is attached to the switch mechanism and rises or falls with the water level. When the liquid reaches a pre-set high or low point, the float triggers the internal switch to open or close the circuit — automatically controlling connected pumps or alarms without any user intervention.\u003c\/p\u003e\n\n\u003ch2\u003eIdeal Applications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eResidential water storage tanks\u003c\/li\u003e\n  \u003cli\u003eIndustrial liquid reservoirs and sumps\u003c\/li\u003e\n  \u003cli\u003eWater pump automatic ON\/OFF control\u003c\/li\u003e\n  \u003cli\u003eIrrigation and water management systems\u003c\/li\u003e\n  \u003cli\u003eAquariums and liquid processing equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eLearn more: \u003ca href=\"https:\/\/www.osha.gov\/personal-protective-equipment\" target=\"_blank\" rel=\"noopener\"\u003eOSHA on personal protective equipment\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What voltage is this water tank float level switch compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: The float level switch (Model ST-70AB) is compatible with both AC 110V and AC 220V, making it suitable for use in different regions and a wide range of household or industrial electrical systems.\u003c\/p\u003e\n\u003ch4\u003eQ: Can this float switch be used in both home and industrial water systems?\u003c\/h4\u003e\n\u003cp\u003eA: Yes.
